- WISCONSIN SHOE Application filed January 18, 1933. Serial No. 652,306.

The present invention relates in general to improvements in the art ofmanufacturing shoes, and relates more specifically to improvements inthe construction of socalled Goodyear welt shoes.

Generally stated, an object of the invention is to provide a durable andcomfortable shoe of the Goodyear welt type, which is devoid of nails andwhich may be manufactured at minimum cost.

A more specific object of the invention is to provide a new and usefulcushion shoe structure which may be readily produced without undesirablechange or enlargement in factory equipment, and which may. be rapidlyreproduced in quantity.

Another specific object of the invention is to provide a simple andstrong heel construction for shoes of the Goodyear welt type, which isentirely nailless, and which is moreover soft and resilient to thetread.

A further specific object of the invention is to provide an improvedshoe which will constantly retain its natural shape, and which is builtup of a minimum number of relatively simple parts.

Still another specific object of the'invention is'to provide a new,method of forming and of attaching a heel to a shoe by stitching andcementing, without danger of subsequent detachment of the heel.

These and other objects and advantages will be apparent from thefollowing detailed description.

A clear conception of one embodiment of the invention and of the mode ofconstruct.- ing Goodyear welt shoes in accordance with the improvement,may be had by'referring to the drawing accompanying and forming a partof this specification in which like reference characters designate thesame or similar parts in the various views.

Fig. 1 is a central longitudinal section through one of the improvedshoes, showing the details of the internal construction thereof;

Fig. 2 is a bottom view of the shoe partially assembled, the view beingtaken at I the surface 2 of Fig. 1;

Fig. 3 is another bottom view of the shoe more completely assembled, theview being taken at the lower outsole surface 3 of Fig. 1;

Fig. 4 is still another bottom view of the shoe in a still morecompleted stage of as sembly, the view being taken at the surface 4 ofFig.1; and

Fig. 5 is a transverse section through the heel of the shoe, taken alongthe vertical line 5-5 of Fig. 1.

As previously indicated, the present invention is particularlyadvantageous when applied to a Goodyear welt type of shoe, of naillessconstruction, although some of the novel features may be more generallyapplicable to other types of footwear.

Referring especially to Fi s. 1 and 5 of the drawing the improved s oecomprises in general an upper 8 having a lining 9 and tinuous integraldownwardly projecting inseam flange or ridge 12; a welt'13 extending'entirely around the lower portion of the upper 8 and around the insole11;-a resilient cushion pad 14 substantially filling the cavity in thelower portion of the insole 11 formed by the continuous ridge 12; anoutsole 15 extending throughout the area beneath the welt 13, insole 11and pad 1:4; and a heel structure consisting of heel base 16 and a lowerheel 17 attached in superimposed relation to the rear portion of theoutsole 15.

As-above indicated, the upper 8, lining 9 and counter 10 are of ordinaryconstruction, and these elements are firmly secured to the flange orinseam ridge 12 0f the insole 11'- and to the welt 13 by means of inseamstitching 19 which extends entirely around the shoe. The resilientcushioning pad l l may be formed of any suitable springy material suchas sponge rubber, and this. pad may be of substantially uniformthickness suflicient to fill the cavity formed by the ridge 12 withoutprojecting downwardly beyond the latter. In order to permit breathing ofthe rubber pad 14 and to thereby enhance the resiliency of the sole,

5 this shank stiffener a transverse drum 22 formed -of any soft sheetmaterial such as upper leather, may be cemented. The drum 22 preferablycompletely covers the heel portion of the cushion pad 14 and welt 13,and also extends longitudinally of the shoe b'c neath the support 21 asshown in Figs.- 1 and 2. The function of the drum 22 is to temporarilyhold the cushion pad 14 and the arch support 21, and to subsequentlyprovide a flexible support for the heel portion of the pad, simulatingthe head of a drum.

The outsole is shown in detail in Figs. 1 and 3, and comprises apiece ofsole leather or other suitable material having substantially uniformthickness, and being provided at its heel portion with an opening 23,which may be circular or any other desired form. Within this opening 23is located an auxiliarycushioning pad 24 of sponge rubber or the like,the upper surface of which coacts directly with thedrum 22 and the lowersurface of which lies flush with the bottom surface of the outsole 15.The function of this auxiliary pad is to provide additional resiliencyto the tread of a wearer, 'at the heel portion of the shoe by providinga double cushion or heel seat. The forward portion of the outsole, fromone side of the heel breast to the other, may be attached to the Welt 13by the usual stitching 25,'and the attachment of the heel portion willbe later explained. r

The heel base 16 may be formed of solo leather and has a thin binder 26of relatively soft and porous material attached thereto as by cementing,and the upper surface of the base 16 is also preferably cemented to theadjacent lower surface of the outsole 15. The base 16 and binder 26 areadditionally rigidly attached to the heel portion of the shoe, bystitching 27 passing through the binder 26, base 16, drum 22 and welt13, and running around the heel from the breast on one side of theshoeto the heel breast on the opposite side. In some cases it may also bedesirable to carry this stitching 27 inwardly up to the shank stiffener21, along the forward portion of the heel. The lower heel 17 which maybe formed of any suitable wear resisting material such as rubber orleather,is finally attached to the binder 26 by means of cement, and thebinder functions to provide a perfect union between the parts by virtueof its porosity and adaptability to absorb and to retain the cement orglue.

- .During the manufacture of shoes in accordance with the presentimprovement, the

' upper 8, lining 9, insole 11 and welt 13, are

first assembled and united by the inseam stitching 19, after which thecushion pad 14 may be inserted and cemented within the cavity formed bythe ridge 12 of the insole. The support 21 and drum 22 may be nextapplied, the latter being cemented in place. The outsole 15 may then besewed to the welt 13 by the stitching 25, after which the heel base 16and binder 26 are cemented to the rear portion of the outsole 15 andsubsequently permanently attached thereto and to the welt by the finalstitching 27. To complete the shoe structure, the lower heel 17 isfinally attached to the binder 26 by cementing or gluing, thus providinga final construction which is entirely devoid of nails.

Fromthe foregoing description, it will be apparent that the presentinvention, besides providing a strong and durable shoe structure of theGoodyear welt type, which is entirely devoid of nails, also provides forample cushioning of the entire sole. The

cushioning pad 14 is relatively inexpensive.

and is effectively maintained in position by the inseam ridge 12 of theinsole 11, and the additional cushioning at the heel portion afforded bythe drum 22 and pad 24, greatly enhances the heel tread comfort. Thecementing and stitching of the heel ,base 16 provides for rigidattachment thereof to the shoe, and .the use of a binder 26 alsoprovides simple and effective means for finally attaching the lower heel17. The improved shoes by virtue of their simplicity, can be readilyproduced without extraordinary factory equipment and have provenextremely comfortablein actual use.

It should be understood that it is not desired to limit the invention tothe exact details of shoe construction and assembly herein shown anddescribed, for various modifications within the scope of the appendedclaims may occur to persons skilled in the art.

It is claimed and desired to secure by Letters Patent:

1. In a shoe, the combination with an insole, welt and outsole, of asponge rubber cushion pad disposed in the outsole near the heel portionof the shoe beneath the insole, and a flexible drum spanning said padand sewed to the heel portion of the welt.
